This paper reviews definitions of audio-visual synchrony and examines their empirical behaviour on test sets up to 200 times larger than used by other authors. The results give new insights into the practical utility of existing synchrony definitions and justify application of audio-visual synchrony techniques to the problem of active speaker localisation in broadcast video. Performance is eval...

To improve the vehicle performance such as ride comfort and road handling, the active suspension system should be used. However, the current active suspension system has a high energy consumption therefore reducing the fuel economy. In this paper the vibration excited by road unevenness is treated as a source of mechanical energy. It is being converted into electrical energy to compensate for t...

The authors investigated linguistic relativity effects by examining the semantic effects of grammatical gender (present in Italian but absent in English) in fluent bilingual speakers as compared with monolingual speakers. In an error-induction experiment, they used responses by monolingual speakers to establish a baseline for bilingual speakers and show that gender affects the semantic substitu...

Speaker diarization is an important component of multi-party dialog systems in order to assign speech-signal segments among participants. Diarization may well be viewed as the problem of detecting and tracking speech turns. It is proposed to address this problem by modeling the spatial coincidence of visual and auditory observations and by combining this coincidence model with a dynamic Bayesia...

This paper presents an iterative process for blind speaker indexing based on a HMM. This process detects and adds speakers one after the other to the evolutive HMM (E-HMM). The use of this HMM approach takes advantage of the different components of AMIRAL automatic speaker recognition system (ASR system: frontend processing, learning, loglikelihood ratio computing) from LIA. The proposed soluti...

This article presents a physical biology approach to understanding organization and segregation of bacterial chromosomes. The author uses a “piston” analogy for bacterial chromosomes in a cell, which leads to a phase diagram for the organization of two athermal chains confined in a closed geometry characterized by two length scales (length and width). When applied to rod-shaped bacteria such as...

activity into daily routines. This guide, which is intended for local government managers and other local government leaders, offers strategies for designing communities that support “active aging—active living for older adults. In addition to encouraging physical activity, promoting active aging creates opportunities for older adults to remain active participants in civic life. Active aging ca...

For instrumental quality assessment of speech enhancement systems it is common to process the signal components such as speech and noise independently using the filter coefficients obtained from the combined noisy signal. Thus, specific quality measures can be computed. A specified signal-to-noise ratio (SNR) can be set for the noisy signal by rescaling and adding the signal components. In this...

This paper compares the language of child bilinguals and adult unbalanced bilinguals (heritage speakers) against that of bilingual native speakers of their home language (baseline). We identify four major vectors of correspondence across the language spoken by these three groups. First, all varieties may represent a given linguistic property in a similar way (child bilinguals = adult heritage s...
